The global warming is a serious issue. Its main cause is
the emission of carbon dioxide into the atmosphere. Carbon dioxide constitutes
92.9% of the total volume of greenhouse gas emission in Japan alone, the
amount discharged per capita exceeding 9 t/year. Because the atmospheric
carbon dioxide concentration continues to increase, its reduction is urgent
and must be tackled immediately by the actions of peoples world-wide.

Absorption of atmospheric carbon dioxide by plants, particularly
trees, is vital for the reliable fixation of carbon dioxide. To grow,
trees use photosynthesis, in which water and atmospheric carbon dioxide
are synthesized into carbohydrates. Moreover, carbon dioxide is fixed
as cellulose, in which form it remains for long periods in trees. For
example, the carbon dioxide accumulated in a teak tree with a trunk diameter
of 10cm is 40-50kg, and in one with a diameter of 50cm it is about 5-6
metric tons.

Forests of the world, especially those in the tropical regions
of Southeast Asia, Africa, and South America, are decreasing at an alarming
rate, mainly because of large-scale tree felling and slash-and-burn agriculture.
Once trees have been destroyed, the topsoil erodes, and forestlands become
wastelands.

It is imperative that we regenerate forests to preserve natural
environments in addition to stopping global warming. TGG therefore has
taken the initiative of planting trees in order to restore forests in
Southeast Asia.

Teak Cutting

It is essential to promote the generation and growth of the
root, one of the most important plant organs, in order to produce saplings
from cuttings. TGG has developed the novel hormones TGG01 and TGG02 which
promote strong root formation on tree cuttings and has established an
efficient method of their use in the mass production of saplings for reforestation.
This method enables us to generate a large number of saplings and carry
out large-scale reforestation.

Mass Production of Teak Saplings by Using TGG01 & TGG02

The period after which the trees planted in our project will
be cut is more than twice that generally used by other enterprises in
current reforestation projects. The amount of carbon dioxide fixed by
and accumulated in reforested trees increases with time, but if trees
are cut after a short growth period sufficient carbon dioxide fixation
and accumulation do not occur.

We define reforestation as the regeneration of forests that
provide the optimum absorption of carbon dioxide and accumulation as carbohydrates.
We therefore sponsor long-term reforestation projects in order to reduce
atmospheric carbon dioxide by storage in trees.

Reforestation promotes preservation of the environment and
provides economic aid to indigenous peoples. This is done by employing
local people to manage reforestation plots and by returning to the country
the profits from selling mature teak to the country. Furthermore, means
are proposed by which local people get income by carrying out reforestation.

If they can obtain monetary profits by supporting reforestation,
then unnecessary destruction of restored forests and harmful slash-and
burn agriculture can be prevented. In this way, forests generated by reforestation
projects will both protect the environment and enrich the lives of native
peoples.
